During the New Sith Wars, academies were divided into four levels of student potential—Force sensitive Sith warriors and marauders were sent to some, potential Sith assassins and spies to other worlds that have allied with the Sith against the Republic, potential Sith Acolytes and adepts to others, with the academy on Korriban being reserved only for potential Sith Masters or Sith Lords. In the academy on Korriban, there were six students for each Master.
